"She's a sister from the same mister, he's a brother from another mother," joked Kody Brown, the father of 13 children and the husband of three wives, as he goofed around with his children in the first episode of TLC's new series "Sister Wives."

The series premiered at 10 p.m. Sunday night on TLC and features a polygamist Mormon family living in Utah.

I thought the initial novelty of polygamy would wear off in the show's first few minutes, leaving me bored watching a family's everyday life. Instead, I found the Brown family's most mundane actions to be the most intriguing and the concept of plural marriage so shocking that I was entertained for the entire hour-long episode.

Although his unkempt hairstyle, intense stares and inability to communicate with his children caused Kody to come across as slightly creepy, I had to admire the precision with which he runs his household and provides for a family of 16 people.

The house operates like a well-oiled machine, and the wives praise polygamy because it allows them to divide responsibilities. The benefits are clear when Kody's second wife, Janelle, is able to maintain her career while Christine, the third wife, takes care of the children and the home during the day.

Meri, wife number one, praises polygamy for the security it provides in the case of a tragedy. After Meri's sister, also a polygamist, died from cancer, her sister wives stepped in to raise her children as their own.

Each wife lives with her children in one of the home's three wings, and Kody switches between the wings on a rotating sleeping schedule.

When asked what she thinks about her husband being intimate with one of her sister wives, a very pregnant Christine exclaims, "Well gosh darn, he better!"

Throughout the episode, I couldn't help but imagine myself in the same situation, and despite the benefits seen on the show, the concept continued to blow my mind. I wondered, how could those women be such great friends and share a husband without getting jealous?

The women say that the struggles that come with polygamy have made all of them, including Kody, better people.

Some of the best insight comes from the children. Many of the older girls said they wouldn't change the way they've grown up but still plan to live a life of monogamy.

The episode culminates with a big announcement: sixteen years after his most recent marriage to Chrstine, Kody plans to bring a fourth wife into the family.

Robyn, Kody's 31-year-old fiancee, has three children from a previous marriage, is six years younger than the youngest sister wife and seems considerably different than them.

"I'm glad he's getting a trophy wife. He's a great guy, he deserves a cute girl," said Christine about Robyn joining the family.

See what happens as the Brown family adjusts to Robyn's presence, Sundays at 10 p.m. on TLC.
